Further objects will appear from the toliowing description taken inconnection with the accompanying drawing in which:

Figure 2 is oi the same; i t

Figure 3 is a central transverse section of reservoir.

Figure -.t is a side elevation of one of the bearing sleeves; and

Figure is an illustration of screening mechanism to which the vibratingmechanism of this invention may he applied.

The vibrating mechanism of this invert tion is designed for use inconnection with a screening device such as is shown in Figure thereonand supporting a screening medium Spanning the fran1e2 at aninteri'nedlate structiou which will be reliable in servic hottomthereoiadapted to providean oil reservoir. A threaded opening 17 in the bottomprovides for the attachment of a drain pipe or drain plug not shown.Thesleeves E) and also their linings may be provided with openings 18 inthe upper portion thereof to catch the splash of oil and deliver the ati l longitudinal section same to the bearing. Drain openings 19 may ialso be provided to return the used oil to the The shaft 11 which isadapted to run in the bearings 10, is provided near the middle thereorwith an enlarged portion 20 on which hulountcd in the upper par ismounted a vibrator cam 21. The cam 21 may be secured against rotation onthe shaft by a pin 22 engaging an eccentric bore 23 in the cam. Theenlarged portion 20 runs between the two bearing members and serves tocenter the shaft so as to aline the cam 21. 5 in which 1 designates. abase or support The shaft 11 may be arranged to. project which carries aframe 2 mounted at an angle from one end of the housing to be equippedwith a' driving pulley 24-. or other suitable means of connection to asource of power. portion thereof is a bridge 4. The bore 7 whichprovides a seat for the Mounted on the bridge iby means of bolts sleeve9 is made la e enough so that the 5 or other suitable fastenings is ahousing 6 adapted to house and support the driving mechanism. Thehousing 6 is formed. with a bore 7 extending lengthwise thereof and wisethrough the bore 7. traversing a pair of bridges 8 extending am 21 maypass cndwise therethrough so that the shaft with the cam assembledthereon may he removed from the housing endt of the housing 7transversely across the housing near the bot 6 is a pivot pin 25provided with a reduced portion 26. at its middle part adapted to retomthereof.

Removably fitting the bore 7 at each end of ceive the hollow bearing 270f a vibrating lever 28. The lever 28 fits the reduced portion 26 ot thepivot pin so as to be confined between shoulders thereon, and the pin 25is provided with adjusting nuts 29 at bothends thcieoi by means of whichthe pin may he and each is provided with an enlarged head shifted so asto adjust the lever 28 to proper or flange 12 fitting a counter bore inthe end of thehousing 6 as shown in Figure 2. Each sleeve is furtherprovided with a pair of ears 13 adapted to receive a pair of clamp ingbolts 14 for securing the sleeves in position in the housing, bolts 14:being threaded the housing 6 is a sleeve 9 lined on its interior withbabbitt 10 or other'suitable bearing material and providing bearing forThe sleeves 9 are formed with cylindrical portions fitting the bore 7 adrive shaft 11.

alincmcnt with the cam 21.

One end of the lever 28 may be equipped with. a follower 30 adapted toengage the cam 21 to he vibrated thereby. The other end of this lever isprovided with a socket adapt cd to receive the upper end of a stem 31eeve opposite whose lower end is connected in any suitable manner withthe screening medium 3. The upper end of the stem 31 is provided with ahead 32 adjustable along the stem by means of a nut 33' and engaged by aspring 34 which rests in a socket 35 on the housing 6. The spring 34-serves to tension the stem 31 and to maintain the follower 30' inengagement with the cam 21. The tension of this spring may be adjustedby means of the nut '33 to any suitable value to give the requiredvibration. A closure 36 of a flexible sheet of rubber is provided toclose the housing 6 against the entrance of dust and dirt. The lever 28may be arranged to project through the closure 36 which, being flexible,will permit vibration of the lever. In thee-operation of this device thesame mayv be driven by a belt from a suitable ,source of power, notshown, engaging the pulley 24, or by other suitable driving means.Rotation of the shaft 11 drives the cam 21 so as to set the follower 30and the lever 28 into vibration, the lever rocks about the pivot pin 25.This lever in turn sets the stem 31 into vibration so as to vihate thescreen 3. The cam rotating in the oil in the reservoir 16 providessplash lubrication for the internal working parts. The oil splashes upinto the openings 18 from which it is fed to the bearings, the used. oildraining back through the openings 19.

The construction. is such that when re pairs are required it is onlynecessary to remove one of the sleeves 9 whereby the shaft 11 may beremoved endwise from the housing with the sleeve, the cam 21 passingthrough the bore 7 By this construction, therefore, i't'is not necessaryto remove the cam from the shaft before the same may be removed from thehousing, both the cam and shaft assembled may be removed together. It isof course, much more convenient'to remove the'cam from the shaft afterthe same has been removed from the hous- Also rebabbitting of thebearings may be easily accomplished by simply removing the sleeves 9,the housing 6 remaining in place on the bridge 4.

It is obvious that various changes may be made in the details ofconstruction without departingfrom the spirit of this invention; it isto be understood, therefore, that this invention is not to be limited tothe specific details shown and described.

. Having thus described the invention what 7 is claimed is:
